As we disdiscussed

Outer Sphere Complex -

Complexes in which outer (nd) orbitals are used in hybridisation (sp3 d2) 

- wherein

For example: \left [ Co\;Cl_{6} \right ]^{4-}

 

 NH_{3} is work as weak field liagand with N_{i} huce \left [ N_{i} \left ( NH_{3} \right )_{6}\right ]^{2+} is outer orbital complex with hybridisation sp^{3}d^{2}.
